no, I meant the question where you had to write the ionic equation for a reaction?


It was a titration so it was H(+) + 0H(-) makes H20

H+(aq) + OH-(aq) H2O(l)

Spoke to all of my friends and they got 1.25
What was the ionic equation for neutralisation?

I got HCl^+ + NaOH^- ---> H20 :/

Phenolphthalene, although I doubt it carries any marks for perfect spelling.

I was surprised they had that as the indicator considering how difficult it is to spell xD

Was this a multiple choice or what?

You could of written methyl orange, but I wouldn't have known the colour change myself.

Im not sure but i dont think it was methly organe, the acid was dilute and methyl orange is used for a strong acid because it goes from orange to red... not 100 percent sure though
